Check Engine Light Due to Pinched Leak Detection Pump Vacuum Lines on Dodge Neon

Problem Description and Possible Solution

If a Check Engine Light illuminates indicating leak detection pump (LDP) failure, the cause is often pinched or disconnected vacuum lines to the pump. Vacuum lines should be inspected before replacing the leak detection pump. Contamination (carbon or debris) in the pump can cause failure and any hoses should be cleared before a new pump is installed.
